Pi-Hole 5.1 - pihole -c (bug)

If I put this in the wrong place, I apologize. Not certain how to submit a bug. I just updated to 5.1 and pihole -c shows FTL offline. I have looked at the code and the reason is the file /var/run/pihole-FTL.port is empty. If you populate the file with the correct informaton, then pihole -c will work echo 4711 > /var/run/pihole-FTL.port pihole -c
